Eftersom anestesi påverkar homeostasen är det alltid förenat med risker. Mätning av anestesidjup, en term som kan delas upp i hypnosgrad och analgesigrad, har diskuterats sedan anestesins födelse. Trots det saknas fortfarande en objektiv mätmetod för detta och de parametrar som används idag tycks inte reflektera inte graden av medvetande direkt. Bispectral Index (BIS) är en mätmetod baserad på en algoritm framtagen genom att studera elektroencefalogram (EEG) hos hundratals människor i vaket tillstånd och under anestesi. Metoden omvandlar EEG-aktivitet i hjärnan till en siffra som speglar hypnosdjupet mellan 0-100, där 100 representerar en helt vaken patient och 0 EEG-tystnad. BIS-värden mellan 40-60 indikerar på människa ett kirurgiskt anestesidjup.

Studies have shown that air pollution, as well as bark fissure depth and sun exposure of a tree can have an effect on lichen growth as well as abundance of lichen species. The aim of this study was to find out the relative importance of these factors. 211 oaks in south eastern Sweden were surveyed for presence of 17 lichen species, as well as the total number of lichen species. Half of the trees were situated in urban areas and half in the countryside. For each tree the bark fissure depth was measured and the sun exposure of the trunk was estimated.

The plants in the genus Elatine are characteristic for oligo and mesotrophic lakes. This study focuses on Elatine hexandra one of the four species in Sweden. It is stated as vulnerable by the National Environment Agency and a conservation plan with guidelines to preserve the plant in Sweden is under preparation. There have been a few previous studies investigating this plant in other countries but this is the first one for Sweden. The aim of this study was to investigate the distribution, growth and reproduction of E.

The Kverneland Ecomat and The Ecomat Seeder has been tested in three different field studies. All the studies were conducted on soils with different clay content during 2005 in Säby outside Uppsala. In one of the trial spring ploughing with the Ecomat and spring ploughing and seeding with Ecomat Seeder were compared with conventional autumn mouldboard ploughing and spring mouldboard ploughing to conventional depth (22-23 cm). In this study the quality of the seedbed, the number of emerged plants and weeds, the pentration resistance and the yield were examined. Shallow spring ploughing (10 cm) with the Kverneland Ecomat has shown to be a good alternative to conventional autumn ploughing when growing spring crops. During the season 2005 tilling with the Ecomat resulted in a higher yield than conventional ploughing. In 2002-2005 the average yield for shallow spring ploughing was 4 percent higher than after conventional autumn mouldboard ploughing and 10 percent higher than after spring mouldboard ploughing to conventional depth (22-23 cm). In the other two studies, ploughing to different depth in the autumn with the Ecomat was compared with conventional mouldboard ploughing and stubble discing.

Generell anestesi kan ges som inhalationsanestesi eller total intravenös anestesi (TIVA). En förutsägbar anestesi med snabbt uppvaknande och bibehållen vakenhet är en högt önskvärd egenskap oavsett anestesiform. Det råder en klinisk och vetenskaplig diskussion om vilken anestesiform som ger snabbast tidig postoperativ återhämtning. syftet med studien var att jämföra patienters tidiga postoperativa återhämtning efter inhalationsanestesi respektive efter total intravenös anestesi (TIVA). Metoden var en litteraturstudie baserad på 15 vetenskapliga artiklar.

After parturition the energy demand for milk production is greater then the energy provided from the diet. The cow mobilises therefore body tissues to compensate for the energy loss. Live weight and body condition scores decreases as a consequence of the mobilisation. The aim of this study was to analyse the relationship between body condition score, live weight and subcutaneous fat depth measured by ultrasound and the changes during the lactation. Possible differences between Swedish Holstein (SLB) and Swedish Red and White Cattle (SRB) were also investigated.

Fuel wood is currently the third largest assortment from the forest in Sweden after pulpwood and lumber. Branches and tops i.e. logging residues are one of the assortments of fuel wood which is a common by-product after harvesting nowadays. The way to utilize, disintegrate and transport the logging residues varies between northern and southern Sweden. Branches and tops are collected throughout the year at appropriate stands, but are consumed mainly wintertime.

Habitat selection of migratory brown trout at the upper reaches of River Vindelälven, wasstudied in September during the pre-spawning period. The fish migrate from down- orupriver lakes for spawning in the river and data was collected by habitat mapping andradio-telemetry. Habitat selection of fish was analysed with preference curves andstatistical modelling, using the physical variables; depth, stream velocity and streambedsubstrate. Preference curves were derived by comparing fish habitat use with their nearbyavailable environment while the statistical modelling aimed to answer three main questions.1) Do the trout have a specific preference of depth, water velocity and streambed substrate?2) Is there any difference in habitat selection between sexes? 3) Is there a shift in habitatselection over time? The preference curves indicated that trout favored water depths of 1-2m, velocity compositions characterized as glides (c.

The Swedish Transport Administration has, and manages, a database containing information of the status of road condition on all paved and governmental operated Swedish roads. The purpose of the database is to support the Pavement Management System (PMS). The PMS is used to identify sections of roads where there is a need for treatment, how to allocate resources and to get a general picture of the state of the road network condition. All major treatments should be reported which has not always been done.The road condition is measured using a number of indicators on e.g. the roads unevenness.

ABSTRACTThe fauna of the Lower Cambrian is far from fully understood, as is the environment of that epoch. Some of the most crucial moments in the history of evolution takes place during this epoch; the Cambrian explosion and the appearance of ecosystems as we know them. That makes it an important period to investigate. Doing so, the Lower Cambrian offers a lot of problems, one of which is that body fossils are seldom preserved. That has often left us with trace fossils to create an image of the Lower Cambrian life, but also some bedrock features such as ripple marks.The main purpose of this work has been to investigate the possibilities of relating the wave lengths and forms of recent wave-generated ripples to fossil ones, and also to evaluate the methods for that kind of comparison.

Dystocia, or difficult birth, is a commonly seen complication to natural birth in veterinary hospitals. Although other methods of resolving dystocia exist, 60 % of dystocias will need to undergo caesarean section. To perform a caesarean section, the bitch will have to undergo anesthesia. The purpose of this literary study was to provide a deeper understanding regarding how the physiologic changes that occur during pregnancy influence anesthetic management in the bitch and puppies. Which anesthetic drugs and drug combinations indicated was also investigated as well as how a veterinary nurse can optimize care of the mother throughout the procedure and how resuscitation of the puppies should be carried out for best possible outcome.

This student report is a literature study about cardiac insufficiency in cats and it is written mainly for veterinary nurses. It is about cats with an underlying heart disease that has led to an incompensated heart failure.It presents a general basis on normal anatomy and physiology, and also how to make the diagnosis, therapy and intensive care.The student report is also about the role of the veterinary nurse during the process of the disease, how to help the veterinarian in the best way, how to handle anesthesia in cats with a heart disease, which factors that can have a significant matter in feeding, and what advices to give to a pet owner with a cat with a incompensated heart failure..

Bakgrund: Kejsarsnitt har blivit vanligare, orsaken kan vara medicinska indikationer, men också förlossningsrädsla. Att kvinnor som föder barn vaginalt får en bättre upplevelse om de får stöd av en medmänniska är välkänt. Studier av kvinnor som föder barn med planerade kejsarsnitt visar att de också behöver stöd. Detta stöd ges framför allt av anestesisjuksköterskor eftersom barnmorskan är sterilklädd.Syfte: Syftet var att beskriva hur anestesisjuksköterskan ger stöd till den födande kvinnan vid planerat kejsarsnitt i spinalanestesi.Metod: En empirisk, deskriptiv studie med kvalitativ ansats genomfördes. Fem anestesisjuksköterskor intervjuades.

A today common soil reinforcement method is the installation of lime-cement columns. Lime-cement columns have been used since the 1970?s and have been a useful method for stabilizing soil at great depths. It is mostly used for stabilizing road and railway embankments because the method is economically viable and the columns are easy to install. The total costs for the installation of the lime-cement columns is dependent on the numbers of installed columns, what percentage of lime and cement that has been used and the pattern in which the columns has been installed.
